Was patting Ollie, my Golden Retriever when I felt a big bump around (what would be) his shoulder. I thought at first it was part of his skin clumped up but it didn't go away. I pressed down on it and he didn't react. He doesn't act different either. I'll bring him to the vet on Monday. Supposedly today but I don't have a way to get him there. I hope it's nothing. I'm scared.
